Biogas generators, raws li cov khoom siv uas hloov cov roj combustible uas tsim los ntawm anaerobic fermentation ntawm biomass rau hauv hluav taws xob lub zog, ua lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob niaj hnub.Lawv cia siab rau cov microbial decomposition ntawm cov organic pov tseg nyob rau hauv ib puag ncig kaw los tsim biogas, feem ntau yog tsim los ntawm methane. Cov biogas no yog siv los tsav lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob sab hauv lossis roj turbine, paub txog kev hloov pauv ntawm cov tshuaj siv hluav taws xob rau hauv hluav taws xob hluav taws xob. Cov thev naus laus zis no qhia txog qhov tseem ceeb ntawm ib puag ncig thiab kev lag luam muaj txiaj ntsig hauv kev siv hluav taws xob tauj dua tshiab, kev tsim hluav taws xob nyob deb nroog, thiab kev kho cov dej khib nyiab hauv kev lag luam.
Los ntawm txoj kev xav ua haujlwm, kev ua haujlwm ntawm lub tshuab hluav taws xob biogas tuaj yeem muab faib ua ob theem tseem ceeb: kev npaj roj thiab tsim hluav taws xob. Hauv theem kev npaj roj, cov khoom siv organic xws li cov tsiaj txhu, cov quav cab, cov khib nyiab hauv chav ua noj, thiab cov sludge hauv nroog decompose rau hauv biogas raws li qhov kub thiab txias, av noo, thiab anaerobic tej yam kev mob los ntawm kev sib koom ua ke ntawm cov kua qaub- ua thiab cov kab mob methanogenic. Cov khoom tseem ceeb ntawm cov roj no yog methane (feem ntau 50% -75% los ntawm ntim) thiab carbon dioxide, nrog me me ntawm impurities xws li hydrogen sulfide. Nyob rau hauv lub zog tsim theem, purified biogas nkag mus rau hauv lub combustion chamber ntawm lub internal combustion engine, sib tov nrog huab cua, thiab kub hnyiab mus ua kom muaj siab - kub, siab - roj. Cov roj no tsav lub piston lossis turbine, uas tig lub tshuab hluav taws xob rotor kom tawm hluav taws xob. Nyob ntawm txoj kev siv cov cua sov, cov tshuab hluav taws xob biogas tuaj yeem muab faib ua cov pa roj- hluav taws xob hluav taws xob hluav taws xob hluav taws xob sab hauv hluav taws xob, cov khoom siv hluav taws xob roj turbine, thiab cov khoom siv hluav taws xob pov tseg ua ke nrog lub voj voog. Ntawm cov no, cov roj- hluav taws xob sab hauv combustion engine yog qhov siv dav tshaj plaws, uas yog pib sai sai - nce thiab muaj zog load adaptability.
Cov yam ntxwv ntawm cov tshuab hluav taws xob biogas tau tshwm sim hauv ntau yam. Ua ntej, lub zog renewability thiab ib puag ncig tus phooj ywg. Nws cov roj los ntawm cov khoom pov tseg rov ua dua tshiab, txo kev cia siab ntawm fossil fuels. Tsis tas li ntawd, cov txheej txheem siv tau zoo txo qis cov pa hluav taws xob ncaj qha ntawm tsev cog khoom xws li methane, yog li ua tiav cov txiaj ntsig txo qis. Thib ob, kev siv cov peev txheej siab ua haujlwm. Cov khoom siv hluav taws xob pov tseg thaum lub sijhawm tsim hluav taws xob tuaj yeem rov qab los ntawm cov khoom siv hluav taws xob rau cov cua sov thiab rwb thaiv tsev ntawm cov khoom siv hluav taws xob anaerobic, muab cov dej kub rau kev tsim khoom thiab siv hauv tsev, lossis hauv cheeb tsam cua sov, txhim kho kev siv hluav taws xob tag nrho. Thib peb, kev ua haujlwm ruaj khov thiab yoog raws. Cov chav nyob niaj hnub no tau nruab nrog lub tshuab hluav taws xob tsis siv neeg, kev tswj ceev ceev, tawg- pov thawj, thiab cov pa roj purification systems, uas tuaj yeem hloov mus rau qhov hloov pauv hauv biogas muaj pes tsawg leeg thiab siab, ua kom muaj kev ua haujlwm tsis tu ncua thiab ruaj khov. Thib plaub, lawv muab qhov zoo ntawm cov khoom siv hluav taws xob decentralized. Piv nrog rau qhov loj-cov chaw tsim hluav taws xob hauv nruab nrab, cov cuab yeej siv hluav taws xob biogas hloov tau yooj yim hauv cov nplai thiab tsim nyog rau kev tsim kho nyob ze thaj chaw uas muaj cov organic pov tseg, xws li cov tsiaj txhu ua liaj ua teb, cov chaw kho dej phwj tuaj, thiab cov chaw ua liaj ua teb, txo qis kev sib kis thiab kev faib tawm.
Daim ntawv thov thaj chaw tau nthuav dav tas li. Nyob rau hauv cov cheeb tsam nyob deb nroog, biogas generators ua ke nrog tsev neeg los yog regional biogas tej yaam num tuaj yeem muab hluav taws xob thiab cua sov rau cov neeg ua liaj ua teb, txhim kho lawv lub zog. Hauv kev ua liaj ua teb, kev sib xyaw ua ke ntawm cov chiv thiab tsim hluav taws xob hauv cov tsiaj txhu loj hauv -cov tsiaj txhu ua liaj ua teb daws teeb meem ib puag ncig cov pa phem thiab tsim cov nyiaj tau los ntxiv. Hauv kev lag luam, cov dej khib nyiab organic los ntawm kev ua zaub mov, brewing, thiab papermaking industries tuaj yeem anaerobically zom los tsim biogas rau lub zog tsim hluav taws xob, ua tiav ob lub hom phiaj ntawm kev tswj cov pa phem thiab lub zog rov qab. Hauv cov nroog, co-kev ua haujlwm hauv nroog sludge thiab cov khib nyiab hauv chav ua noj rau kev tsim hluav taws xob pab txhawb kev tsim kho "zero-cov nroog khib nyiab" thiab txhawb kev lag luam ncig.
Nyob rau hauv cov nqe lus ntawm kev loj hlob tiam sis, biogas generators yog evolving mus rau ntau dua efficiency, txawj ntse, thiab huv si ua hauj lwm. Txoj kev loj hlob ntawm high-kev ua tau zoo combustion technology thiab qis- tso pa tawm tom qab- cov cuab yeej kho mob ntxiv txo cov pa phem xws li nitrogen oxides thiab sulfides; daim ntawv thov ntawm kev saib xyuas ntse thiab kev ua haujlwm ntawm cov chaw taws teeb thiab kev saib xyuas kev txhim kho kev nyab xeeb thiab kev tswj xyuas kev ua haujlwm ntawm chav tsev; thiab kev koom ua ke nrog lub zog cia thiab microgrid thev naus laus zis txhim kho qhov yooj yim thiab kev ntseeg siab ntawm cov tshuab hluav taws xob sib faib. Lub caij no, kev sib txawv ntawm cov khoom siv raw thiab kev nce qib hauv cov thev naus laus zis ua ntej tau nthuav dav ntau yam ntawm cov khoom siv pov tseg, txhim kho roj ntau ruaj khov thiab cov txiaj ntsig kev lag luam.
Zuag qhia tag nrho, biogas generators, los ntawm kev siv cov peev txheej ntawm cov organic pov tseg, tau tsim txoj hauv kev zoo rau kev sib koom tes ntawm kev tsim hluav taws xob thiab kev tiv thaiv ib puag ncig. Nrog rau kev nce qib thev naus laus zis thiab cov qauv siv tshiab, lawv lub luag haujlwm hauv kev hloov pauv hluav taws xob thoob ntiaj teb thiab cov tswv yim kev txhim kho kom ruaj khov yuav ua kom muaj txiaj ntsig zoo, muab kev txhawb nqa zoo rau kev tsim kom muaj tsawg - carbon, ncig kev lag luam thiab zej zog.
